Overview
The Rolex GMT-Master II reference 126711CHNR pairs a 40 mm Oystersteel case with Everose gold accents in the brand's signature two-tone Rolesor construction, finished with a black dial. Introduced in 2018, it represents the contemporary expression of Rolex's long-running professional GMT line, built around the in-house Calibre 3285. The combination of robust stainless steel and warm rose gold places it at the intersection of tool-watch utility and dressy versatility.
History
The GMT-Master lineage traces back to the 1950s, when Rolex developed the original reference in collaboration with a major international airline to meet the needs of long-haul aviators and navigators. The GMT-Master II generation refined the concept by introducing an independently adjustable local-hour hand, allowing the wearer to set a second time zone without disrupting the running minutes or the 24-hour hand. The 126711CHNR arrived in 2018 as part of a broader generational update to the GMT-Master II family, bringing with it the then-new Calibre 3285 and a redesigned Oyster bracelet with the Oysterlock clasp. Its two-tone Rolesor identity continues a tradition of offering the GMT-Master II in mixed-material configurations that broaden its appeal beyond purely professional contexts.
Notable points
- Rolesor construction combines an Oystersteel case body with Everose gold crown, bezel, and bracelet centre links — a hallmark of Rolex's two-tone philosophy.
- The black "CHNR" dial designation reflects the use of a black ceramic (Cerachrom) bezel insert alongside the dark dial, contributing to the reference's cohesive monochromatic-and-gold aesthetic.
- Calibre 3285 features a Chronergy escapement, a paramagnetic blue Parachrom hairspring, and a power reserve of approximately 70 hours — a significant advance over the earlier Cal. 3186 it replaced.
- The bidirectional rotatable bezel with its 24-hour graduated Cerachrom insert allows at-a-glance reading of a third time zone, a practical feature that has defined the GMT-Master II since its introduction.
- The reference sits on an Oyster bracelet with the Oysterlock safety clasp and Easylink comfort extension system, details that reflect the model's continued positioning as a serious travel instrument.
